MR27V452D is a 4Mbit electrically programmable read-only memory with page mode. Its configuration can be electrically switched between 262,144 word x 16bit and 524,288 word x 8bit. MR27V452D operates on a single +3.3V power supply and is TTL compatible. MR27V452D provides Page mode which can greatly reduce the read access time. Since MR27V452D operates asynchronously, external clocks are not required, making this device easy-to-use. MR27V452D is suitable as large-capacity fixed memory for microcomputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 40-pin DIP, 40-pin SOP or 44-pin TSOP packages.
The MR27V452D is a 4Mbit electrically Programmable Read-Only Memory (PROM) featuring page mode operation to reduce access time. It operates on a single +3.3V power supply and is TTL compatible, making it suitable for microcomputers and data terminals.
